well i recieved my ipv mini and subtank and i am impressed! the build quality of the subtank seems really nice. i primed the coil and filled the tank and am now vaping around 27 watts.
my only problem is i cant taste very much.. not at 10 watts, 15, 20, etc.. i think i need to let my taste buds fix themselves. i smoked my last cigarette about 2 hours ago so hopefully it gets better!!
When I started using ecigs it took a while for my taste buds to come around. Some juices are lighter (but just as good) in flavor then others, I bet the taste is there. IMO (seeing as you keep going back to wanting a Kayfun) the Lemo is 100 times better and it can be had for waaaaay cheaper. You can get an authentic Lemo from Fasttech for less then $40 and from other online US vendors for less then $50 from what I have seen. Not only does the price make it more desirable but the airflow is much better, it looks a lot nicer IMO and the flavor and vapor production both beat any Kayfun both authentic and clone I have ever tried. The lemo is simply a stunning RBA and the only tank I am using anymore (phased out everything except my rDNA, Flask and Lemos along with mech mods and drippers lol.)
Its fine to learn to build on the ST Mini. Take a look at how it comes rigged up and try to replicate that build again if you wish or just use it the coil it comes with. I personally enjoy the vape the ST Mini gives more with the pre made heads then any coil/wick I put in it.
